Paulina Lake (left) and East Lake (in the distance) mark the depression of the Newberry Volcano Caldera. Unlike Crater Lake, Newberry's caldera is not the result of a single climactic eruption, but rather a number of eruptions over time. Newberry is also different from Crater Lake in that there are many more post-caldera lava flows and cones that fill the caldera. The most obvious of these is the relatively young, and unvegetated Big Obsidian Flow - a rhyolite coulee that covers a large part of the southern caldera.
